v0.4.7-alpha.1

[ClassicOldSong]

GPU priority hack

This is a pre-release, it might cause unexpected issues.

This release does not change anything to the configurations, so you can safely downgrade to the stable release if you find it problematic.

Please report any findings you have with this version to the corresponding discussion:

1. Does it solve or decrease HAGS freezing?
2. Does it affect game performance?
3. Does it improve stuttering issues?
4. Have you noticed any other things get affected?

Please report with your system configurations including CPU/GPU model, memory type and speed, operating system and version, and GPU driver version.

Hello,

• No Performance Degradation:
  I haven’t experienced any degradation compared to previous versions, everything remains smooth. But I didn't have any problems before.

• Tested Games:
  The Alters: Pushed to maximum graphics settings, with and without FG (no issues).
  Oblivion Remastered: Heavily modded with pushed graphics and RTX, using DLSS 4 MFG x3 (still smooth with occasional stuttering observed, but this is not new and unrelated to the GPU priority hack or Apollo: likely game specific).

• Host Setup:
  7800X3D (core curve -30 all cores)
  5090 (OC undervolt + 80% limited + core curve) & 580.88 driver version
  64 Go DDR5 6000 (latency optimized)
  Win 11 24h2 LTSC
  Steam overlay enabled with built-in performance overlay during stream

• Streaming:
  4K
  120 fps
  AV1 10bits SDR
  300 Mbit/s bitrate

• Latencies:
  I would like others to confirm this, but I have the impression that the encoding latency remains extremely stable (the maximum stays below 6 ms and the average rarely exceeds 4 ms). Even though I have done everything possible to maintain 100% GPU usage with or without FG.

My second client device is an iPad 13 Pro M4 with VoidLink. I haven't tested it. I'll come back again if I've missed anything.

[ClassicOldSong]

Thank you, what codec are you using?

[HakanFly]

AV1 codec (with 10 bits SDR)

[kayti]

Hello,

No Performance Degradation:
I haven’t experienced any degradation compared to previous versions, everything remains smooth.

Tested Games:
Final Fantasy 16 (FSR, Frame Generation)
Cyberpunk 2077 (RT, DLSS, AMD Frame Generation, Path Tracing, Textures and Details High/Ultra)

Host Setup:
R9 7900
RTX 3080 & 576.80 driver version
32 GB DDR5 6000
Win 11 24h2 PRO
RTSS overlay for testing framerates etc

Streaming:
3440x1440
120 fps
HEVC HDR
400 Mbit/s bitrate
HAGS enabled

Latencies:
Like previous user said, host processing is stable, match perfectly framerate of game (in my case 60 for FF16 and around 70 I got for Cyberpunk, 3080 doesn't have enough juice for more ;))
Year or so ago, when I played Cyberpunk, with HAGS on, similar settings like right now were unplayable + was only getting around 40 frames :D Stream was very choppy and was freezing easily. Now it is smooth, stable and responsive. Huge improvement.

FF16 also feels more smooth/stable framerate, before had problem to hit 60 fps (was hovering between 55 to 60, both for stream and in game FPS, where stream was often "lagging" behind game FPS by 2-3 frames), now solid 60 for both game and stream, except few situations where game heavily drops FPS :) But stream FPS follow game FPS.

I didn't experience any stream related stutter.

EDIT. Works well with VRR too, my display reports refresh rates matching stream.

[ClassicOldSong]

Thank you

[VirtualGIT20]

Hello,

Here's what i've found:

Host Setup:
i9 9900k
3070 8GB & 580.88 driver version
32 Gb DDR4 3200 MT/s
Win 11 24h2
RTSS for monitoring resources and performance, 60FPS frame limit

Client Setup:
Nvidia Shield Pro
Artemis (latest version available)
Smoothest frame pacing option
1440p, 60fps with "double refresh rate" option enabled
150Mbit/s bitrate
HEVC HDR

Tested Games:
The Last of Us 2
Ghost of Tsushima
Cyberpunk 2077

Compared the two version "back-to-back"

• Does it solve or decrease the frequency of HAGS freezing?
  Seems like it, i've managed to play for more than 30 minutes continuosly at +7700 MB VRAM usage without any freeze while before it would freeze after 2/3 minutes.

• Does it affect game performance?
  The games that I've used in the test were configured to use a little over 7200MB of VRAM at MAX to remain stable.
  I've tried to encrease the quality of the texture to see if the stream would freeze, and it didn't.
  However, there was a degradation in performance from 5 to 10 fps avg compared to latest stable version, especially when approaching the limit of VRAM (from 7500MB and on) where I've experienced big stutters (like half a second).
  In general, even with previous settings, I've found more instability in games than with previous version.

• Does it improve stuttering issues?
  No difference found.
  In my setup, if I dont run the "smoothest" option in Artemis I experience some microstuttering (already confirmed that host hz = client hz), I've tried "low latency" and "balanced" frame pacing options but the microstutter is still present, so with my setup I didnt find any difference.

• Regarding latency:
  Didn't feel any difference.

[ClassicOldSong]

Thank you for taking the time to test!

You can run the frame skipping test in TestUFO while streaming to see if it loses frames, and maybe get the pattern of the stuttering to better understand what's happening.

[VirtualGIT20]

Did it, took around 100 pictures during the frame skipping test while streaming on client, and I couldn’t find a single lost frame.
At this point, I really don’t know what else to try.

[kayti]

iGPU is enabled? In my case, Intel software (installed with intel GPU driver) had some "metric report" service, which was causing in some games small stutters.

[VirtualGIT20]

Thanks for the suggestion.

I've recently enabled my iGPU for the first time ever to shave off some VRAM usage from secondary apps possibly running in the background (like Playnite, Discord, Spotify) but I did the majority of my testing with it disabled.
In my case, it didn't make any difference.

EDIT:
To be clear, the microstuttering that I'm experiencing are not being captured from RTSS frametime graph so are not directly related to games but to the stream (in fact, I don't have any problem when gaming directly on my PC)

[VirtualGIT20]

UPDATE:
A little update after some hours of gaming.
Yesterday I played The Last of Us Part II for about 3 hours straight and experienced 2 major freezes, similar to what happened with the previous version.

During both freezes, VRAM usage was under control (around 7100–7200 MB). However, I was able to keep playing even in some cutscenes where usage spiked above 7500 MB.
So, while it does seem a bit more resilient than before, it still eventually crashes after some time.

Let me know if I can run additional tests or provide logs to help.

[Monolithxxx]

so, to roll back, I just need to install the previous version and that's it? does it always work this way, or specifically in this build? Because often when I want to install the previous version, I delete the new one and have to reconnect the devices.

[ClassicOldSong]

Yes, just install and all settings are kept.

When the major/minor version bumps it's better to uninstall and reinstall.

But usually there's no need to rollback, regressions like the stuttering in 0.4.0 is rare.

[WesleyVanNeck]

Would this update solve some latency issues with encoding and mobile data our less latency at least on amd

[ClassicOldSong]

It won't solve network latency, whether it improves encoding latency depends. You can try and report your findings.

[BatJoe]

I have not had HAGS freezes with other builds so I'd be curious to know why some get it others don't? I thought I heard it was a VRAM issue? I have a 5090 so VRAM is not really a problem.

I'd be curious to know how this may or may not improve stuttering. The issue will be most won't know how to actually tell or if placebo is a factor.

@ClassicOldSong Are you able to provide more info what this GPU priority hack does? As I understand Sunshine/Apollo should normally set high priority when running by default?

[ClassicOldSong]

Sets absolute priority instead of relative priority. This hack was already being used long ago in OBS's official builds, but they have hide the actual flag used for some unknown reason.

[Cattleist]

I've been having issues re-installing Apollo where I'm unable to access zlib1.dll when installing. I've also tried running the installer in Admin mode to no avail. I've ignored the prompt and it appears to install okay, but the latency seems to be much worse. Any idea on this?

[ClassicOldSong]

Rare case but it shouldn't affect latency. Maybe something else changed?

[Cattleist]

Admittedly, W11 did just run an update before I tried updating. Maybe that's a factor?

[ClassicOldSong]

Try to rule out network changes first, and open stats overlay on the client to see what's happening.

[Cattleist]

After troubleshooting I discovered two things:

zlib1.dll was in use by some Logitech software. Ending this task was able to resolve the accessibility error I was encountering on install/updates. However this didn't affect performance.

Restarting my router did appear to fix the latency/Bad Connection problems that were occurring. Sorry!

[jonch919]

Findings:
Don't notice any difference at all. Still not very smooth like GFE used to be. (Don't know exactly what hags freezing refers to in this case). No latency issues. No direct stuttering, just not smooth.
Games tested so far: Wuthering Waves only, mid to high settings, dlss auto, rtx on or off, stable 60 fps

PC:
Win10 pro 10.0.19045
i5 12400F
GF 3070, 580.97, afterburner auto oc
DDR4 32GB 3600
60 fps gaming, rtss limit at 60, double refresh (240), vsync fast, only v-display active, hosts native res 3200x1440@120(240)

Client:
Samsung s21 ultra, 5gz wifi
Latest Artemis
Hevc (av1 doest seen to be supported), ~20ms decode, 20-200 mbit feels equal in performance
Native res, 120hz etc
Note: all frame pacing modes feels virtually identical. Not laggy, but choppy or unsmooth. Feels closer 30 fps gaming.

Update:
This build introduces major slowdowns after a while of streaming. Downgrading...

Update 2:
After downgrading it's much smother than before upgrading. Pretty smooth even.

[Pradinhodot]

What did you mean by the second update? And which version did you downgrade to?

[jonch919]

0.4.6.
After upgrading newest Nvidia drivers yesterday, everything is super smooth. Don't notice any difference between 4.6 or 4.7

[BatJoe]

I wonder would future builds be better to incorporate this as an adjustable setting instead?

[gmbhneo]

So in direct comparison from old to new version, things work much smoother and lags get less frequent on my end.

Games Tested:

Will test more later, but for now, things work much better on my end. Smoother and with less visual stuttering, I would say.

[Soladus]

I found a bug, if the TV is on 120hz but through the nvidia control panel set moonlight to work in 1/2 refrash rate (otherwise the TV can not be forced to work smoothly in moonlight and other games, they stutter, and such a solution makes games to work very smoothly and have faster controller responsiveness) and run the game (the division 2) in the settings to select window mode, then after a while the delay increases insanely a lot, such a problem is not noticed on version 0.3.7 hotfix 1

sorry for eng, not my native

[Soladus]

You can easily and quickly reproduce this problem by leaving the stream and returning again, and the decoding time immediately increases from 0.30 to 135.xx

[Soladus]

[ClassicOldSong]

Never had this problem and cannot reproduce.

Like I said before, everything related to "decoding" is a client side issue, it has nothing to do with the host. Maybe disable the frame limit on Moonlight and stream directly in 60fps instead?

[Soladus]

I got it. I have 60fps in moonlight and a 60fps limit on the host for the game, but I set 120hz on the TV and 1/2 refrash rate on the client. This happens when the game is in windowed mode on the host. Nevertheless, thank you! I will experiment

[Soladus]

I found a solution, it turns out that you still need to enable vsync in moonlight, but I don't understand why, because I was using 120hz 1/2 to avoid using vsync and reduce input lag.

[MohannedElfatih]

Used to get random frequent freezes, but they no longer happen with this version. I haven't noticed any smoothness/visual issues. Sometimes the whole stream freezes then disconnects but that might be a client issue (I just reconnect and it works fine)

Tested Games:
Sword of the Sea: Epic settings.

[aerodomigue]

Hello,

I've tested the v0.4.7-alpha.1 pre-release and I'm happy to report a significant improvement. About 90% of the freezes I previously experienced have disappeared.

Feedback on Key Points:

• HAGS freezing: The issue is almost entirely resolved for me. Previously, I had frequent freezes primarily in Forza Horizon 5, but they are now nearly gone. I also had freezing issues with Stellar Blade on the non-beta version of Apollo, but there were no freezes at all in this version.
• Game performance: Performance was stable across all the games I tested.
• Stuttering issues: I did not notice any new or worsening stuttering.
• Other noticeable effects: The overall experience was much smoother and more stable.

Games Tested:

• Valheim
• phasmophobia
• Stellar Blade
• Forza Horizon 5
• Factorio
• The last of us 1 and 2
• Resident Evil Village
• BF6 (Open Beta)

My Configuration:

• Server:
  • CPU: Ryzen 5700X3D
  • GPU: RTX 3080 10GB
  • Memory: 32GB DDR4 (3200MHz)
  • OS: Windows 11 IoT Enterprise LTSC (24H2)
  • GPU Driver: 581.08

  • Device: Mac mini M4 (16GB)
  • Monitor: 3440x1440 144Hz
  • Video: H265 (YUV 4:4:4), 150mbps

Thanks for your hard work on this!

[dannycanham]

Hello,

No Performance Degradation:
No issues before and no issues during. Appears to handle streaming during heavy loading, shader compilation and maybe during high CPU usage better - like during lots of cars on a track in Horizon 5. Appears to reduce the worst dips in Maximum encoding latency resulting in better average encoding times and less variance. As well as the maximum latency generally being more stable if I was to average the Maximum encoding latency times over one circuit of Horizon 5 the Maximum latency improves by about 0.5ms (10%) which is huge.

Tested Games:
Forza Horizon 5
Marvel Heros

Host Setup:
9800X3D
5090. Overclock and boost limit. Ultra low latency mode. G-sync. 240fps limit through the nVidia app.

Streaming 2:
M4 iPad Pro 13 with Voidlink also runs well. 500mbps. 2752x2064. 120fps.

[gmbhneo]

I am having these weird dips every like 5 seconds. I've made a video, hope that helps.

I see this in all games, and it looks like it's the Nvidia Card doing something (overshooting or something) that causes this. To me, it looks like the card "forgets" its limits and overshoots, which causes stuttering since it needs to become normal again.

[gmbhneo]

I never messed with nvcp settings. One thing I have noticed is, enabling Nvidia Reflex in-game and disable VSync could greatly help with smoothness

Tested, works pretty well now. However, after about 10-15 minutes, the connection is "freezing" for about 2-3 seconds. This happens about every 5 Minutes and is getting worse over time. Any idea about this?

By wifi? If so, do you happen to have an intel ax210? Then there's a well-known issue with this card, which stutters every 10 minutes due to global scanning. There's a custom firmware that allows you to disable this feature, and it has resolved all the stutters on my card.

Yes, Wi-Fi. I am using an Intel(R) Wi-Fi 6 AX200 160MHz and also tested a MediaTek MT7925. Both seem to have different issues. Intel one seems to have the global scanning. So, can you give me any link or info about it?

The MediaTek has issues in terms of stuttering my PC in general, since it's influencing my GPU Power, like stated in this video: https://www.youtube.com/watch?v=YWTZkB9rVU0 by JayzTwoCents. It is my Motherboards Wi-Fi card. So I've disabled it. But I would love to use it since it's Wi-Fi 7 and the intel one is just 6E. (Yes, my AP is 7 - Ubiquiti U7 Pro Max)

Thank you for sharing. However, I am not able to download and unzip the driver to test it. Also, the benefits seem not to include AX200 which I use. So no luck for me. The only solution I know thus far is to get a Qualcomm Card to replace my MediaTek since most intel chips don't work with AMD...

Anyway, thank you all for helping! Looks like I need to wait for MediaTek to update their drivers, since even the latest ones got issues with scanning every 10 minutes or so ...

[Soladus]

Use 7zip app. As far as I know, 200 is no different from 210, they are almost identical, and the versions 2xxx are listed in the name, so everything from 2 is suitable. Maybe I'm wrong.

[Soladus]

My 9800x3D works with the Intel AX210

[BatJoe]

@gmbhneo

It should be noted Elden Ring on PC on both local and streaming has pretty known issues with stutter and performance. Its just not a good title on any platform, really.

And yeah, AMD+NVidia seems to cause more issues than Intel+Nvidia. I have a 14900k and 5090 and no major issues. In fact, the latest Aretmis and Apollo builds by @ClassicOldSong are probably the smoothest things have been.

[0xItx]

[jakehonour93-hue]

Hi,

Few issues for me, reported below. I have not had these issues before.

Host Setup:
7800x3d
9070XT latest drivers
Hags ON
Latest W11 Update
Virtual Display @ 4K, 120refresh rate, RTSS to cap 60hz
All other monitors switched off
Connected via ETHERNET on a 1Gb network

Client Setup:

Moonlight - Latest Pre Release in Dev Mode
4K, 60fps
7.1 Surround Sound selected
150Mbit/s bitrate
HEVC
Non HDR
Connected via ETHERNET on a 1Gb network

Tested Games:
Oblivion
Red Dead 2

Does it solve or decrease the frequency of HAGS freezing?
I have not experienced any freezing at all.

Does it affect game performance?
Yes - whilst my stats are perfect with low latency and no dropped frames, I have input issues. When the input issues occur, button presses are delayed and things feel slow, although the picture is perfect. I get the below logs where it spams ASYNC call back issues:

Rebooting the HOST resolves this issue, this is what the logs say WITHOUT the problem occurring:

Does it improve stuttering issues?
I have no stuttering, but I have issues with the input being delayed, with the async errors occurring

Regarding latency:
No difference in latency when it works, when there is an issue, the latency is no different on the performance overlay, but clear delay.

If you need any more information please ask.

[ClassicOldSong]

Maybe a new driver will resolve the issue if it's happening on the host side. I just read that Asus has some bad drivers affecting performance, and AMD has CPU design flaws causing time de-sync between different CCDs, which all can contribute to weird host side performance.

[jakehonour93-hue]

Thanks for your response - I did not have the issue until I installed this pre release.

My CPU only has one CCD and I do not have any ASUS parts.

I will install the stable version, if everything works OK it is an issue with the changes in this pre release. I will let you know.

[ClassicOldSong]

The pre-release only changed the capture and encoding priority, which in theory should not affect anything related to input. If it still affects these parts, that means AMD has more issues than we previously know.

[jakehonour93-hue]

Thanks for your reply,

As you said, In theory your changes wouldn't affect input, but in practice does it not interact with the hosts GPU scheduling? which could be causing async callback errors? The async errors are what is causing the input delay, as all my latencies, host and client are normal and there are no spikes.

It also runs perfectly at times, and then the issue will occur where a reboot will temporarily resolve it.

You have asked if having HAGS enabled is causing issues with the pre release, and this is an issue I am seeing so I want to report it.

If you do not want to investigate further, that is fine, but the issue did not occur on the stable release, and rebooting temporarily clears it, which suggests the problem is linked to the pre-release changes affecting task scheduling on the host.

Thank you for your hard work so far, it is greatly appreciated!

[ClassicOldSong]

It's not that I don't want, but I can't. Windows is pretty much a black box, so is the Xbox platform. There're many many cases that Apollo works perfectly previously but after a driver update, it broke, or starts stuttering, or previously it didn't run perfectly but after a driver or system upgrade, it magically works better. It's just not what I can control, and if I would inspect, either I would spend a great amount of money to buy each party's tech support, or throw lots of energy into reverse engineering and the effort will likely go vain just by the next driver/system upgrade.

Have you veirfied with other clients to see if the issue is persistent?

[HNYPN]

I’m super thankful for the Artemis/Apollo app. I use it almost every day and it works perfektly without Problems
Thank you ! 🫶🏼

[Alexandre-Tridon]

Hi, idk if I'm the only one experiencing stuttering at certain key moments in games.

Host setup:

AMD Ryzen 5 3600
NVIDIA GeForce GTX 1660s
RAM: 16 GB @ 3200 MHz
Windows 11 24H2 Pro

When I played Life is Strange, I noticed stuttering occurs when I'm in menus or when I'm examining objects, like the journal that Max carries in the game. I found a way to reproduce this stuttering: I just have to look at the credits and the stuttering appears. I tried the same thing with The Last of Us and the stuttering occurs there too. Could this be related to 30 FPS content?

[ClassicOldSong]

Have you tried using a frame limiter?

[Alexandre-Tridon]

I did, with the Nvidia panel control (first at 60 fps and also at 30 fps). I've tested my TV refresh rate with testufo and also tried different configurations of V-Sync/G-Sync, frame pacing, encoder, etc. I've also tested fullscreen and borderless windowed modes.

[Alexandre-Tridon]

I'm coming back here to share that the stuttering was actually caused by an incorrect video bitrate setting (either too high or too low). It’s tricky to determine the right bitrate, and I’ve also noticed—strangely enough—that my stream works better over 5GHz Wi-Fi with a 20 MHz bandwidth (for stability) than when my TCL TV is connected via Ethernet. That seems really odd to me. Anyway, thanks for the follow-up and the development work!

[gerbillinae]

I used to get freezes every 10-30 seconds. That has been fixed by this update

[Randomtidus]

Still have microstutters every few seconds, i dont have this problem with sunshine. Cant revert back to 0.3.7 hotfix 1 anymore, because it wont install the sudovda. This is still the last version wich worked flawless

Ryzen 7 5700x3d

[ClassicOldSong]

Maybe it's caused by your monitor's auto switch input source feature

[TinoSM]

Tested Games:
MGS Snake eater

I was getting sttuters in 0.4.6, with 0.4.7.alpha1, i've played for 1hour and no sttuter.
Ok it came back, not sure what's the trigger, its some random sttuter but perfectly playable, anyways sameas prev version

MacOS is not the most reliable client tho, it could be that a system restart also fixed it, but anyways 0.4.7alpha1 went fine

[TinoSM]

Update here, Bf6 becomes unplayable with it

I tried BF6 (which eats my CPU a lot) and with this version it plays like CRAP, constant freezeing, I can only sustain like 30Mbps bitrate to play smooth, with 0.4.6 (rolled back) it is like 120Mbps

It works fine in "solo" mode (low CPU usage) and menus

[Soladus]

I don't have such a problem, I just recently streamed on steam deck oled and everything is fine.

[TinoSM]

I think mine is somehow related to very high CPU usage. I do play online redsec (i'm just testing, im mainly remote gamer so if it's not playable I won't buy the game)

[Arakiiel]

Tested games:
Dragons dogma 2

Does it solve or decrease HAGS freezing?
It did not, I'm still getting regular freezes like the previous version
At 400Mbps the HAGS problem was extreme and constant, dropping to 300Mbps or 150Mbps I am still getting the HAGS problem when opening menus or when there is a big scene transition. The game continues to run and I can here the audio and can hear that the controller is being registered based on the audio. The on screen logs freeze as well so based on the logs it looks like everything has been running fine but obvously its not, I'm not even sure if it is the hags issue or there is just an issue with the moonlight app on xbox.

Does it affect game performance?
Didn't noticed any difference

Does it improve stuttering issues?
Didn't noticed any stuttering

Have you noticed any other things get affected?
No

GPU priority hack

This is a pre-release, it might cause unexpected issues.

This release does not change anything to the configurations, so you can safely downgrade to the stable release if you find it problematic.

Please report any findings you have with this version to the corresponding discussion:

1. Does it solve or decrease HAGS freezing?
2. Does it affect game performance?
3. Does it improve stuttering issues?
4. Have you noticed any other things get affected?

Please report with your system configurations including CPU/GPU model, memory type and speed, operating system and version, and GPU driver version.

This discussion was created from the release v0.4.7-alpha.1.

Hi! Sorry to write in this thread, I don't want to create unnecessary topics. Throughout my time, I've used dozens of devices with different operating systems and specifications, and I'm tired of listing them all :) I've realized that out of everything I've tried, only the steam deck oled and a PC with an Nvidia GPU work smoothly, and even then, only if I enable 1/2 refresh rate through the inspector. Everything else has issues with vsync and micro-stutters. I'm getting to the point. Could you please tell me how you use moonlight on devices, specifically on windows, (because it's on this os that I see these issues), and how often you experience micro-stutters, and what settings you use? I've tried everything described in the wiki, but I haven't been able to achieve perfection. On linux, it varies, but it's often better than on the windows client. These stutters are particularly noticeable when the camera is smoothly rotating, and they're subtle, but i notice them. Right now, I can't achieve this smoothness on legion go s. All limits and so on are met

Thanks for the response. I didn't quite understand what exactly can be tried on the host with apollo?

Thank you! But I use dummy plug and this for vd :(

Do I understand correctly that oled is better at handling micro stutters? Because I've tried using bazzite on the rog ally x and steamos on the legion go s, but they don't work as perfectly as the steam deck oled, and I don't understand why. The only thing that comes to mind is the difference in displays

[ClassicOldSong]

Not really, it depends on the display controller, which can be vastly different from device to device.

But I use dummy plug and this for vd :(

Why not give virtual display a try :)

[Soladus]

I tried it a long time ago, on another device, and there was no difference :) and the display showed stable 60hz in ufo, plus I have a host with amd :)

Is it possible to implement 1/2 refresh rate in the app? so that it works similarly to the setting in the nvidia inspector, but for amd there is no such option at all, and it might help for 120hz screens. I understand that you haven't made Moonlight, so this is a theoretical question.

Hello there, I am joining this discussion to report an improvement for my use case.

System Configuration

KVM virtual machine with Windows 11 25H2 guest os with VirtIO drivers and GPU pass-through; the system was customized through Atlas OS version 0.5.0

• 4 cores/8 threads of a Ryzen 7 3700X
• 16 GB of DDR4 RAM at 3200MT/s
• EVGA GTX 1080Ti FTW3 with "overclock BIOS"

I set Apollo to always create a virtual display when my Moonlight Desktop client connect, since the Virtual Machine does not use a dummy display dongle nor a physical display attached to the GPU.

The streaming settings of the client are 1440p at 60 FPS with 70Mbpps of bitrate over an Ethernet connection on both sides; also I chose to use borderless windowed display mode and to disable V-Sync.

Findings report

• HAGS: on my current configuration, disabling or enabling it does not seem to make any difference
• game performance: I experienced a lot of game crashes on "Kena: Bridge of Spirits" with Apollo 0.4.6, but after updating to this alpha I did not experience that again; more specifically, the whole guest system crashed and the only way to interact again with the virtual machine was to force a power off or a reset. This behavior did not occur on previous games like "Injustice 2" or "Split Fiction", but that was on a previous Windows 11 version and on a previous Nvidia driver version, so I am not sure if I just got an unlucky permutation of software components in this case
• stuttering issues: nothing changed in this regard, as in I am not experiencing stutters in the streaming configured as described above

In general, this alpha works flawlessly on Windows 11 25H2 for my specific use case (Atlas customization, inside a VM)
